You really can't go wrong with any of the scents! I got this car diffuser version to try out all the scents & no regrets! I used the Swiss Chateu for the car. Japanese Ryokan for my bedroom. All the scents are not overpowering, doesn't give me a headache. Maybe because it's in this kind of diffuser bottle, so its a faint pleasant scent that doesn't attack my nose. Lol love it.My favourite is Japanese Ryokan (light powdery floral scent). Its very subtle, very pleasant, rather relaxing.
Followed by Maldives Villa & English Country Inn, it smells like a fresh slightly citrusy scent. I prefer these scents for bathrooms.
Swiss Chateu smells like fresh men's cologne, so those looking for a more musculine scent may prefer this.
